Elephants
The WWF believes that culling—another way of saying “killing”—elephants is acceptable, as is the trade in ivory, because the profits that it brings spur governments to keep elephants from going extinct. In 2000, U.S. News & World Report reported that WWF representatives traveled to Nairobi to ask the United Nations to lift the ban on the ivory trade in order to allow a “sustainable harvest of ivory for horns and hunting trophies.”

It's not just seals and elephants but all animals they feel are ok to hunt and test on. Vile bastards! from wickedwildlife website re: elephants culls:

The WWF’s bizarre view—that we must kill some animals now in order to save animals to kill later—has proved false time and again. The trade in ivory has only encouraged rampant poaching, the senseless slaughter of elephants. The WWF tries to duck the issue by falsely stating, “The decision to cull, or to select animals from the herd for removal or death, is indeed an agonizing choice, but it is one made entirely by the governments concerned and there is no international involvement in those decisions.”
